The game was scheduled for Sept. 26 2015 at Rentschler Field with a return game in 2016.
Tennessee and UConn agreed to suspend the series. That 2015 and 2016 games will not happen, and new dates will be determined by 9/26/15 according to UConn.
UConn plays Army, Villanova and is at BYU in the non-conference in 2015.
In 2016, UConn's non-conference schedule has only Virginia on it. The Huskies were scheduled to open up the 2016 in Knoxville.
As far as replacements for 2015, the AAC may move to a 9-game conference schedule in a 12-team conference and that would fill the void.
It is worth noting that the only "Power 5" conference team UConn has scheduled right now is Virginia in 2016.
UConn has non-conference games with BYU and Boise State on tap as well as a series with Army.
